Application filed August 13, 1913.

To all whom it may concern:

Be it known that I, GEORGE A. JOHNSON,

a citizen of the United States, residing at a door packing of durableconstruction and efficient operation.

In the drawings forming-a part of this specification, Figure 1 is across section through the meeting edges of a refrigerator door and thesurrounding wall of the doorframe, showing in cross section the packingdevice in expanded position embodying my invention; Fig. 2 is a planview of a portion of the wall of the door frame surrounding the doorwith my door packing in position, but partly broken away to show thegroove in the door-frame; Fig. 8 is a cross section taken at the meetingedges of the door and surrounding door-frame with the door in closedposition, and showing in cross section my packing device compressed.

Referring to the drawings 1 represents the edge of a hinged door, theremainder thereof being broken away and not shown in the drawings, 5 ahinge securing said door to the door-frame 6. Within the face 7 of thedoor-frame, which is adapted to be met by and engage the face 8 of thedoor 4 upon the closing of the door, is provided a groove 9 extendinglongitudinally of the door-frame, and having a central projecting beador ridge 10 and depressions 11, 11 at either side thereof. Within saidgroove 9 is mounted a spring 15 extending the entire length of thegroove, the said spring having at either edge thereof a curved orrounded portion 12, 12, and being provided with perforations 13, 13 toreceive means, preferably screws 14, 14, engaging the central portion ofsaid spring to the head or ridge 10 in the said Specification of LettersPatent.

groove 9. The said spring is adapted to compress on either side of saidbead within the grooves or channels 11, 11 upon pressure being appliedto the outer face of said spring.

A yielding material 19 is stretched across the said groove 9, andsecured to either side thereof, the said yielding material 19 engagingagainst the spring 15, and preferably comprising a matting 16 and acanvas strip 17, the same being secured to the face 7 of the door-frameby suitable means, preferably the nails 18, 18.

Upon the opening of the door the packing device will assume the positionillustrated in Fig. 1 of the drawing, the spring 15 being expanded, andthe rounded or curved portions 12, 12 thereof forcing the yieldingmaterial 19 outwardly in a taut position. Upon engagement of the face 8of the door against the yielding material 19 on the closing of the doorthe rounded or curved portions 12, 12 of the spring press the yieldingmaterial 19 against the face 8 of the door at points upon said faceopposed to the rounded portions of the spring, the pressure increasingat these points along the rounded portion of the spring until the dooris closed, and the rounded portions of the spring are compressed withinthe depressions 11, 11in either side of the groove 9, as illustrated inFig. 3 of the drawing. Packing strips are unnecessary in my device, thepressure against the yielding material being exerted by the spring alongspaced parallel lines, affording a tight joint between the door anddoor-frame.

Applicant hereby formally acknowledges that a broader claim to thespring support having spaced parallel lines of contact is contained andhas been allowed in his copending application, bearing Serial Number784,042, filed August 11, 1913.

I claim In a door packing of the character described, the combinationwith a door and an adjacent member having meeting edges when the door isin closed position, one of said edges being provided with alongitudinally extending groove, of a strip of flexible materialbridging said groove, and

means for pressing said material outwardly longitudinally extending,central rib to I to thereby form a seal, said means compris- Which saidspring strip is secured.
